backgoround scan capability in trend micro internet security 2007

hi all,
as part of my college project i m doing analysis of several security softwares based on certain parameters(right now i am analyzing trend micro internet security 2007). Background scan is one such parameter, which means that when a scan is initiated(preferably from command line), in this mode, the user (who is a novice) is not confronted with the messages from security software (asking what to do) i.e. when the security software detects a virus while scanning it takes the required action without asking the user. i have been searching for a similar feature in Trend Micro Internet Security 2007, but as of now i haven't had much luck. Can you guys please help me with this?
Any information in this regard would be highly appreciated.

Hi There, I'm not sure about Trend's background scanning capabilities, but if you're looking out for areas where products respond automatically instead of alerting & asking the user what to do, I'd check the firewall (install some common and uncommon programs and see if they trigger firewall alerts), as well as sheilds technology (i think this is venus spy trap in trend).
